BURNER.

SPECIFICATION forming part of Letters Patent NO. 757,653, dated April 19, 1904.

Application filed November 18, 1902. Serial. No. 131,882. (No model.)

To @ZZ wtone t may concern.-

Be it known that I, JOHN DANIEL GRE EN, a citizen of the United States, residing a Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Burner, of which the following is a specification.

This invention relates more particularlyto gas-burners for use in radiators; but it Will be seen by those skilled in the art that it can be employed in various relations and can be used under certain conditionsv as an oil-burner.

The object of the invention is to provide a structure that is extremely simple and compact, being' so arranged that it will gradually heat the gas passed therethrough, mix it with air, and thoroughly commingle the two before being ignited, thus eifecting'thorough combustion and obtaining a maximum heating effect.

The preferred embodiment of the invention is illustrated in the accompanying drawings and is described in the following specification.

It will be apparent, however, upon an inspection of the claims that the invention is open to various changes and modifications.

In the drawings, Figure 1 is a side elevation of the improved burner. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a vertical transverse sectional view.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings. Y

In the embodiment illustrated a casing is employed formed of side walls 10, endwalls 11, and a removable cap 12. Extending longitudinally along the bottom of the casing and arranged exteriorly thereof is a conductingpipe 13, and located within the casing and spaced from the side walls 10 thereof is another conducting-pipe 14. These pipes and casing, with the exception of the cap 12, are preferably cast in one piece, the bores of the pipes extending through the end walls 11, so that said pipes have no direct communication with the interior of the casing.

Secured to one end of the lower pipe 13 is a i supply-pipe, a portion of which is shown at 15, said pipe being attached to any suitable source of gas-supply. The other endvof the pipe 18 is connected with the corresponding end of the pipe 14C by means of an elbow 16, fastened to said pipes by suitable couplings 17, this elbow being located exteriorly of the casing, at one end thereof. Communicating with the interior of the casing and screwed in the end thereof opposite Mthe elbow 16 is a mixer 18, having the usual nozzle 19. This mixer is located between the ends of the pipes 13 and 14 and is connected with the adjacent end of the upper pipe by means of a return-pipe 20.

The pipe 1&1, as already described, is spaced from the side walls 10 of the casing, but is connected thereto by awall 21, extending the length of the casing and dividing the interior thereof into separate compartments having communication through openings or passageways 22, formed in the wall. This wall is furthermore provided contiguous to the edges of the side walls 10 with upstanding lianges V23, which form seats for the lower edges of the cap 12. This cap, as shown in Fig. 3, is semicylindrical in form, being spaced from the pipe 14. It is provided with a plurality of suitable burner-outlets 24, which preferabiy extend from end to end and may be arranged in any desired form. In this structure the pipe 13 constitutes a preliminary heating-chamber for the gas, while the pipe 14 may be properly4 termed a superheatingchamber. Y

In. use, assumingl the burner in operation, the gas will pass through the supply-pipe 15 into the heating chamber or pipe 13, where it will be slightly warmed. Passing through the elbow it will enter the pipe 14 and being nearer the place of ignition will thus be superheated. From the pipe 14 it will pass through the mixer and into the interior of the casing, being commingled with the air. In order to make this commingling thorough, the wall 21 has been provided, for the gas and air will necessarily pass through the small openings 22 and be completely mixed, finally Ending an escape through the burner-openings 24. The wall 21 therefore constitutes a commingling element that is located between the mixer and burner-openings 22; It will be apparent from the accompanying drawings lthat the parts are few and simple, so that the structui'e can be easily and cheaply manufactured; but further than this and of more importance is the gradual heating of the gas and the thorough commingling of it with the air, so that perfect combustion is assured.

From the foregoing it is thought that the construction, operation, and. man y advantages of the herein-described invention will be ap- IO parent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from I5 the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

2O l. In a burner, the combination with a casing, of a perforate commingling-wall extending across the interior of the casing dividing the same into separate compartments, the wall of the casing being provided with burner-outlets that communicate with one of the compartments, and a mixer that communicates with the other compartment, whereby fuel passing through the mixer will pass through the commingling-Wall to the burner-outlets.

2. In a burner, the combination with a casing having a burner-outlet, of `an air-mixer communicating' with the interior of the casing, and a commingling element arranged in the Casing between the mixer and the burner-outlet and comprising a partition-wall extending across the casing and having' passage-ways therethrough.

3. In a burner, the combination with a casing having burner-outlets, of an air-mixer 40 communicating with the interior of the casing', a superheating-chamber arranged within the casing, and a commingling element located in the casing between the mixer and the burneroutlets and comprising' a wall connected with the superheating-chamber and having passage-ways therethrough.

4. In a burner, the combination with a casing having a burner-outlet, of an air-mixer communicating with the interior of the casing,

a supcrheating-chamber extending through the casing and spaced from the side walls thereof, and a commingling-wall connecting the chamber and the casing between the burner-outlet and air-mixer and having passage-ways therethrough. 5 5

5. In a burner, the combination with a casing having a burner-outlet, of an air-mixer communicating' with the interior of the casing and located at one end thereof, a pipe extending through the casing and connected with the mixer, and a wall extendingfrom the pipe to the casing' and having passage-ways therethrough.

6. In a burner, the combination with a casing having end walls and burner-outlets, of spaced conducting-pipes extending from end to end of the casing, an elbow connecting the pipes at one end of the casing and located exteriorly thereof, and a mixer communicating with the interior of the casing and connected with one of the pipes.

7. In a burner, the combination with a casing having end walls and burner-outlets, of spaced conducting-pipes extending from end to end of the casing, an elbow connecting' the 75 pipes at one end of the casing, and a mixer. communicating with the interior of the casing and located between the pipes at the end opposite the elbow, said mixer being connected with one of the pipes. 8O

8. In a burner, the combination with a casing' having' end walls and aremovable cap provided with burner-outlets, of spaced conducting-pipes extendingfrom end to end of the casing, one of said pipes being located along the bottom thereof, an exteriorly-arranged elbow connecting the .pipes at one end of the casing, a mixer communicating with the interior of the casing at the other end and located between the pipes, said mixer being connected with one of the pipes, and a comming'lingwall extending from the inner pipe to the casing' and having passage-ways therethroug'h.

In testimony that I claim the foregoing as my own I have hereto ailixcd my signature in the presence of two witnesses.

JOHN DANIEL GREEN.
